Technical explanations

Technical explanations Technical explanations Technical explanations Standards and regulations The motors comply with the relevant standards and regulations, particularly with the following: Standards and regulations 13 Design efficiency and power factor 22 Progressive coordination of output 14 Restarting during residual field and phase opposition 23 Design version 14 Motor protection 23 Degree of protection 15 Duty types 23 Cooling and ventilation 15 Pole-changing motors 28 Rating plate 15 Energy saving motors as specified in CEMEP 28 Type designation 16 Energy saving motors as specified in...

Technical explanations Technical explanations CSA approval According to the regulations of the “Canadian Standard Association” (CSA), the motors of type series K11R are in the frame size range 56 to 315 approved for rated voltages up to 690 V. They are designated accordingly on the rating plate with the logo shown. Components to be attached or built in must also be listed by CSA or manufactured in accordance with the approval. Explosion-proof motors are subject neither to a UL, cULus nor CSA approval. Motors with legally imposed minimum efficiencies are subject to additional regulations. See...

Technical explanations Technical explanations also indicated on the rating plate or an additional plate. The rating plates are fastened on the housing with grooved drive studs and cannot be lost. They may be made of aluminium or stainless steel (extra price). For additional plates it will be required to consult the manufacturer. Types of construction The most frequently used types of construction are shown in the following table. Other types of construction on request. The type of construction is designated on the nameplate according to Code I, DIN EN 60034-7. Standard motors in sizes 56 – 200...

Technical explanations Vibration behaviour and balancing Bearings having a relubrication device should be relubricated through the lubrication nipple with the motor running and observing the quantity of grease specified The permissible vibration intensities of electrical motors are specified in DIN EN 60034-14. The vibration intensity level A (normal, without designation on the rating plate) is achieved or improved by VEM motors in the basic verVibration intensity level A B Shaft height H Motors installation Free suspension Rigid mounting Free suspension Rigid mounting seff [µm] 25 21 11 - sion....

Technical explanations Bearing control For controlling the condition of the bearings the motors may be equipped with temperature sensors, shock pulse and vibration detectors or prepared for such equipment. The temperature sensors mounted to the bearing points may be of type PT100 which can be of two-, three- or four-wire circuit design. These can be connected either in the main connection box or in separate additional boxes which are fixed to the main terminal box or motor housing depending on construction. The wear monitoring function for the anti-friction bearings as of frame size 132 may be...

Technical explanations Technical explanations Rated output Restarting during residual field and phase opposition The rated output applies to continuous operation as specified in DIN EN 60034-1, related to a coolant temperature of 40 °C and an altitude of ≤ 1000 m above sea level, operating frequency 50 Hz and rated voltage. The series K11R /K21R and K10R /K20R have thermal reserves that enable the following type-dependent continuous loads: – up to 10 % above the rated output at 40 °C coolant temperature – rated output up to 50 °C coolant temperature – rated output at an installation altitude...
